No modems. No SIM plans. No rotation infrastructure. Our open-source proxy-reseller-kit gives you an SDK, a React dashboard, and a full Next.js storefront on top of $4/GB wholesale — so you can ship a branded mobile-proxy business in an afternoon and resell at your own price.
To start a proxy reselling business, get a reseller API key from PROXIES.SX, clone the open-source proxy-reseller-kit (MIT), set your brand and prices in one config file, and deploy. You buy bandwidth wholesale at $4/GB (less at volume) and resell at your own price — typically 2–5×. The gateway runs the 4G/5G fleet; you just mint capped customer keys.

Demand for clean 4G/5G mobile IPs keeps climbing — scraping teams, social-media operators, ad verification, AI agents. But the barrier to supplying them has always been physical: modems, SIM cards, rotation rigs, uptime. The gateway model removes all of that. PROXIES.SX runs the hardware; you sell access. Your only job is branding, pricing, and support — the parts where a focused operator actually adds value.
The kit makes the software side a non-event too. Instead of building key management, usage metering, billing webhooks, and a customer dashboard from scratch, you clone a maintained, security-reviewed codebase and change a config file.
Your margin is the spread. Wholesale drops at volume; you keep the difference minus payment fees.
| Example tier | You sell | Your cost @ $4/GB | Gross spread* |
|---|---|---|---|
| Starter — 5 GB | $35 | $20 | ~$15 |
| Pro — 25 GB | $150 | $100 | ~$50 |
| Scale — 100 GB | $500 | $400 | ~$100 |
*Example pricing ships in the kit's default config — edit it to whatever you want. Spread is before Stripe fees (2.9% + $0.30) and before volume discounts on your wholesale cost. Figures are illustrative, not a guarantee of earnings.
Typed SDK to mint, cap, top-up, rotate, and delete per-customer keys.
Drop-in React dashboard so customers self-serve their keys and usage.
Full starter app: auth, Stripe billing, Postgres, admin + customer views.
MIT licensed — no attribution required. Security-reviewed: parameterized SQL, mandatory Stripe webhook signature verification, idempotent events, server-side-only API keys, database-backed sessions.
From a full storefront to a single REST call, in any language.
Clone apps/starter/, fill .env, set brand + prices in one config file, deploy. A complete branded shop with auth, Stripe, and a customer dashboard.
Drop the React dashboard component into an app you already have. Customers manage their own keys; you keep your existing stack.
Use @proxies-sx/pool-sdk in any Node/TS backend to mint, cap, top-up, rotate, and delete keys programmatically.
Call the reseller endpoints directly from any language with an X-API-Key header. PHP, Go, Python, Ruby — anything that speaks HTTP.
Mint your psx_ reseller API key at client.proxies.sx/account.
git clone the repo, cd apps/starter, copy .env.example → .env.
Set name, colors, logo, support contact, and your price tiers in src/config.ts.
Add your Stripe keys (and optionally an x402 wallet for USDC). Run pnpm db:migrate.
pnpm dev locally, then deploy (Docker or Vercel). Your shop mints capped keys on every sale.
import { ProxiesClient } from '@proxies-sx/pool-sdk';
const proxies = new ProxiesClient({
apiKey: process.env.PROXIES_SX_API_KEY!, // your psx_ reseller key
proxyUsername: process.env.PROXIES_SX_USERNAME!,
});
// On every sale, mint a key scoped to what the customer bought:
const key = await proxies.poolKeys.create({
label: 'customer:alice',
trafficCapGB: 10,
expiresAt: new Date(Date.now() + 60 * 86_400_000).toISOString(),
});
// → hand key.secret (pak_...) to the customer. The gateway meters usage.One endpoint, three pools: -mbl- (stable 4G/5G), -peer- (residential), -any- (auto-pick mobile, fallback residential). Country, session stickiness, and rotation are all set in the proxy username.
The kit ships an x402 flow: an autonomous agent pays in USDC over the HTTP 402 handshake, and your shop mints a pak_ key capped to the payment. A whole new class of customer, no checkout UI required.

Get a reseller API key from PROXIES.SX, clone the open-source proxy-reseller-kit, set your brand and prices in one config file, and deploy. The kit ships an SDK, a React customer dashboard, and a full Next.js storefront with Stripe billing — so a branded mobile-proxy shop runs in an afternoon. You buy bandwidth wholesale at $4/GB (less at volume) and resell it at your own price, typically 2–5×.
It is the official open-source (MIT) toolkit from PROXIES.SX for reselling mobile proxies through the Pool Gateway (gw.proxies.sx:7000). It contains @proxies-sx/pool-sdk, the @proxies-sx/pool-portal-react dashboard component, and a Next.js storefront template. You mint per-customer keys with GB caps and expiry, and the gateway handles the actual proxy traffic.
Margin is the spread between wholesale and your retail price. Wholesale is $4/GB (dropping to $2.40/GB at volume); resellers commonly price at 2–5× that. On a $4/GB cost, selling at $15/GB is roughly a 3.75× markup before Stripe fees (2.9% + $0.30). Your real margin depends on your pricing, volume tier, and churn — these are directional industry ranges, not guarantees.
No. That is the point of the gateway model. PROXIES.SX runs the physical 4G/5G fleet; you connect to a single endpoint (gw.proxies.sx:7000) and mint customer keys via the API. No hardware, no SIM plans, no rotation infrastructure to maintain.
Yes. The kit includes an x402 flow: autonomous agents pay in USDC over the HTTP 402 Payment Required handshake, and the kit mints a pak_ key capped to the payment amount. Same margin structure as card payments, no human in the loop.
